These HGST drives are the first to double today?s SAS interface speed.
Designed for the most demanding applications where "hot" data is accessed
frequently,HGST's new 12Gb/s SAS SSDs help increase input/output per
second (IOPS) and improve response times to mission-critical data in
cloud and traditional IT datacenters environments.

The new Ultrastar 12Gb/s SAS SSD family combines enterprise-grade, 25nm,
MLC NAND flash memory, performance, advanced endurance management
firmware and power loss data management techniques to extend reliability,
endurance and sustained performance over the life of the SSD.

The
SSDs are rated with a 2.0 million hours mean time between failure (MTBF)
specification.

The new Ultrastar SSD800MH 12Gb/s SAS SSD delivers a sequential
throughput with up to 1,200MB/s large block reads, and up to 750MB/s
writes. It also delivers up to 145,000 read and 100,000 write IOPS,
reaching speeds >100 times faster than HDDs.

With this new generation, HGST has also improved its SSD "quality of
service." Quality of service refers to how quickly and efficiently the
SSD can manage and process reads and writes to the drive. Like lanes on a
highway, too much data traffic can cause congestion and slow performance.
In tier 0/1 enterprise applications such as high-frequency trading, every
millisecond counts. HGST uses firmware and controller technology to
significantly improve command completion time requirements. The overall
result is a 50 percent improvement in latency, a 300 percent improvement
in I/O per second (IOPS) writes, and a 2x ? 3x faster throughput compared
to the earlier generation Ultrastar SSD400S SSD.

HGST?s new SSD family also comes with three endurance levels - high
endurance, mainstream endurance and read-intensive endurance. The new
Ultrastar SSD800MH high-endurance SSD rates at 25 full drive writes per
day (DW/D) for five years. The Ultrastar SSD800MM mainstream endurance
SSD rates at 10 DW/D for five years. The read-intensive 1TB Ultrastar
SSD1000MR SSD rates at two DW/D for five years.

HGST is currently qualifying its SSDs with select OEMs. Broader
qualification samples are now available with channel distribution
scheduled in June 2013.

The Ultrastar 12Gb/s SAS SSD family is targeted to achieve a 0.44 percent
annual failure rate (AFR) or two million hour mean-time-between-failure
(MTBF). They are backed by a five-year limited warranty, or the maximum
petabytes written (based on capacity).
